HS402 DIY Oscilloscope V1.7
1 year agoProfile：HS402 is an USB Oscilloscope working with STM32F411 development board.
Open source license: CERN Open Hardware License
Description
A 2 Channel DIY Oscilloscope based on STM32F4x1 Black Pill development board. It provide long memory buffer and high real-time transfer speed. As the HS10X series it keep the best ratio performance/cost/ease to build.
Power consumption is also one of the lowest in the market (~40mA). It can be used only with HScope app for Android.
